HANGER-SUPPORT FOR CONCRETE OEILINGS.

Specifieation'of Letters Patent.

Patented April 9, 1907.

' Application filed. September 19,1906. Serial No. 395.229.

To all whom it may concern:

Be it known that I, ARTHUR J. PERKINS, a citizen of the United States ofAmerica, and a resident of S ringfield, in the county of Hampden andtate of Massachusetts, have invented certain new and useful Improveowingis a full, clear, and exact description.

This invention resides in a hanger-support, preferably made as acasting, to be embedded 1n 0. vertical position in a concrete ceilingand consisting of a hollow body having at the lower portion thereof avertical downwardlyleading opening with ledges at o posit-e sides ofsuch opening, said opening aving a dimension in one direction greaterthan in the other, whereby a hanger-nut may be inserted in said openingand be positioned within the support to rest on said ledges.

The invention furthermore consists in subordinate features orformationsand provisions for advantages hereinafter rendered apparent.

he improved hanger-support is illustrated inthe accompanying drawings,in

Figure l is a vertical sectional view through a concrete ceiling,showing a hangersupport embedded therein' and interlocked therewith, thesaid support having combined therewith a hanger for a pipe. Fig. 2 is avertical section, on a larger scale, through the support and hanger astaken on the line 2 2, Fig.1. Fig. 3 is a similar sectional view, but astaken .on the plane at right angles thereto,

indicated by line 3 3, -Fig. 2. Figs. 4 and 5 are horizontalcross-sections taken onlines 4 4 and 5 5, Fig. 3-. Fig. 6 is an end viewof the support as seen at the'bottom thereof.

Similar characters of reference indicate corresponding parts in all ofthe views.

I may be engaged with and suspemled from In the drawings, A representsthe hangersupport, B Fig. 1 representing a concrete ceiling, in whichthe support is embedded, and C represents one form of a hanger whiching, the said opening, as clearly'seen in Fig. 6, avin g a dimension inpne direction greater.

than in the other.

The lowered chambered portion 0 of the cast-iron or otherwiseconstituted hangersup ort is shownas rectangular in form,

whi e between such rectangular portion and its upper end the casting iscross-sectionally circular, is downwardly tapered,- is made withsidewise extended webs or flanges f f, and has transversely-extendedflanges g get its upper end, such formation and flanges roviding for anefiicient interlocking ofthe anger-support in the. concrete, preventingdisplacement in a downward direction or under any force tending to turnor twist it from its given set'position.

It will be observed that the flanges ff are substantially diametricallyopposed and that the flanges g g are similarly related and that the twosets of flanges are, roughly speaking, arranged in quadrature. Moreover,the

flanges ff and g 9 both project beyond the the body, and the flanges f fare set free of the overhang of the flanges g g. From this arrangeinentflows a very important advantage as follows: As to downward strain, thehori zontal flanges g g bear upon underlying bodies of concrete, whichare not broken up or (llvided by the vertical flanges f f, while, as toa rotative force, these latter flanges are resisted by portions of theconcrete structure which are not subjected to the downward compressionof the flanges g g. The result is a very strong embedding of thehanger-support in the surrounding material.

1* represents a nut, which in the. present instance isshowir as of arectangular form having a distance from side to side greater than thewidth of the opening I), but not quite so great as the length of saidopening, and the thickness of the nut is less than the width of saidopening I), and it is to be understood that in the construction of abuilding having concrete ceilings the hanger-supports are embedded insuitable arrangement in the concrete ceiling, with their lower endsflush,

or substantially so, with the under surface of the co crete which makesthe ceiling, and when .it is desired to mount a hanger the nut isinserted. cdgewise through the opening b within the chamber above theledges d d and then turned flatwise to rest on the ledges, asrepresented in Figs. 3 and 4, whereupon the hanger, having ascrew-threaded or bolt-like shank, may be inserted through the opening band engaged with and screwed through the: threads of the nut more orless far, as de-' sired, for acquiring a reliable supporting of thehanger and the proper adjustment thereof.

It will be perceived that the walls of the rectangular portion of thehanger-body will engage with or be engaged by the nut, so that thelatter will be prevented'from rotating while'the threaded shank of thehanger is screwing therethrough. It is to be noted that lower chamberedportion 0 of the hanger is restricted in extent as-to both lateraldimensions. Preferably these two dimensions are substantially equal, sothat the-chamber will be but little larger horizontally than an ordinaryrectangular nut of the' 'proper size. This construction insures that notonl will the nut be locked againstirotation whilla liO or o ening b.

Tii

ate portion of its hei'ght an internal flange 1',

inclosing an opening permitting the free passage therethrough in anupward direction ofupward and. rotated to causel'itsthreads to engagewith the tapped-portionigof the nut. It Wlll be recognized that i 'isimportant'to provide some such stop or abutment for the nut, else. thelatter --wou ld have to be forced clear to the top of the interior'ofthehanger before the threads of the bolt could secure a purchase. It willbe obvious, however, that a flange is not necessary for the provision ofsuch a seat, as, any suitable form of stop or constriction in the boreof the hanger a short distance above the opening I) would serve theurpose. hie utilityto become available in cases, for -instance,- wherethe ledges might become broken away to lose the nut-support or'in caseswhere" some special hangers having larger shanks might be'desi'rablyused, and it is evident that by inserting a tap or thread cutting toolupwardl through the opening b a thread, as indicate at a: by dottedlines in Fig. 2, may be formed in the inner edge ofthe fla e j toreceive screw engagement therewit of the threaded shank of the hanger ofproperly large'diameter.

or the purpose 111st mentioned it follows that the circular aperturethrough the flange would have to have a smaller diameter than the widthof the opening I) in order that it 6 might fit closely the bolt whichpasses loosely ;slotted, opening and communicating with the bolt isbeing screwed therein, but the nutwill be prevented from slidingside'wise in either direction to a material extent. This is also insuredby limiting the length of theslot f "longitudinally eadin This flange isa provision of possithrough the latteri If the flange serves merely as aseat for the. nut, it is'apparent that such relation between thediameter-of the flange-aperture and the width of the ter minal openingneed not exist.

Hangers havin otherwise than hook for: mations at their ow'er portions'will be pro- .vided for the supporting of various objects from theceiling.

Various changes may be made in the design andshape of the parts'withoutdepart- 'ing from this invention or sacrificing 'any'pf the advantagesthereof, and it"is manifest,v

as well as in ceilings.
